The title compound, previously designated as JDF-2 [Gai-Boyes, Thomas, Wright, Jones, Natarajan, Chen & Xu (1992). J. Phys. Chem. 96, 8206-8209], is an aluminium phosphate (AlPO) with a three-dimensional framework structure consisting of three types of PO 4 tetrahedral unit linked to three crystallographically distinct Al atoms. One of the Al atoms is tetrahedrally coordinated (as AlO 4 ) while the remaining two have distorted trigonal bipyramidal coordination and are linked through a common O atom to form O 4 Al-OH-AlO 4 units. These units are relatively rare features in AlPO frameworks as the Al- and P-containing polyhedra are usually linked in a strictly alternating manner
